Exposed Brick project in Boston . Looking for breathable sealer recommendations.

Plastered late 1800’s wall (117 sq ft) in Boston apartment

Hammer and Dasco Pro 4 in. x 7 in. Brick Set Chisel. Laborious as hell. Horsehair plaster.

More hammer and chisel. Dusty as hell. Used a 3M Full Facepiece Reusable Respirator 6800.

Upgraded to Bosch Bulldog Xtreme 8 Amp 1 in. Corded Variable Speed SDS-Plus and Milwaukee 3 in. x 6 in. SDS-PLUS Hammer Steel Tile Chisel. Way easier than hammer and chisel. Done in one evening. Easiest part of exposing brick. The plaster disposal was the hardest part. Extremely dense and heavy stuff. Lots of fine dust particles.

Started to remove mortar residue from bricks with a drill mounted with Avanti Pro 4 in. x 1 in. Non-Woven Drill Mount Quick-Strip Disc. More dust. Very time consuming. Brick by brick. Went through 3 discs.

This is the wall after discing each brick. Much better but bricks still covered with mortar haze.

Final product. Used a Muriatic acid based product, Sureklean 600, at a ratio of 1 part acid to 10 parts water to get rid of the efflorescence. I used a hose to get the wall super wet before applying the acid with a Tampico brush. I rinsed it with water after 5 min and applied a baking soda to neutralize the acid. Used a gas mask respirator, 3M Organic Vapor/Acid Gas Cartridge/Filter 60923 , and full body coverall while applying. Looking to seal it with breathable product to limit dust and and maybe add a little luster. Any recommendations?
